Abstract. We investigate the nature of trading and sorting induced by the dynamic price mechanism in a competitive durable good market with adverse selection and exogenous entry of traders over time. The model is a dynamic version of Akerlof (1970) . Identical cohorts of durable goods, whose quality is known only to potential sellers, enter the market over time. We show that there exists a cyclical equilibrium where all goods are traded within a finite number of periods after entry. Market failure is reflected in the length of waiting time before trade. The model also provides an explanation of market fluctuations. JEL classification: D82 A propos des marchés de biens durables quand il y a entrée de nouveaux commerçants et sélection adverse. Les auteurs analysent la nature du commerce et du triage engendrés par le mécanisme dynamique des prix dans un marché concurrentiel de biens durables quand il y a sélection adverse et entrée exogène de nouveaux commerçants dans le temps. Ce modèle est une version dynamique du modèle d’ Akerlof (1970) . Des cohortes identiques de biens durables, dont la qualité est connue seulement des vendeurs potentiels, arrivent sur le marché dans le temps. Il semble qu’il y ait plus de commerce actif que ce qui est prévu par un modèle statique. En particulier, on montre qu’il existe un équilibre cyclique où tous les biens sont transigés à l’intérieur d’un nombre fini de périodes après leur arrivage et que, à chaque phase du cycle, l’éventail de qualité des biens transigés s’accroît. Les commerçants qui transigent des produits de plus haute qualité attendent plus longtemps et l’imperfection du marché se traduit par la longueur de temps d’attente avant la transaction. Le modèle fournit aussi une explication des fluctuations du marché. 相似文献

Exit Options in Corporate Finance: Liquidity versus Incentives 总被引:2,自引:0,他引:2
This paper provides a first study of the optimal design of active monitors'exit options in a problem involving a demand for liquidity and costly monitoring of the issuer. Optimal incentives to monitor the issuer may involve restricting the monitor's right to sell her claims on the firm's cash-flow early. But the monitor will then require a liquidity premium for holding such an illiquid claim. In general, therefore, there will be a trade off between incentives and liquidity. The paper highlights a fundamental complementarity between speculative monitoring in financial markets (which increases the informativeness of prices) and active monitoring inside the firm: in financial markets where price discovery is better and securities prices reflect the fundamentals of the issuer better, the incentive cost of greater liquidity may be smaller and active monitoring incentives may be preserved. The paper spells out the conditions under which more or less liquidity is warranted and applies the analysis to shed light on common exit provisions in venture capital financing. 相似文献

Entrepreneurship and Unemployment in the UK 总被引:1,自引:0,他引:1
Roy Thurik 《Scottish journal of political economy》2003,50(3):264-290
The influence of industrial structure, more specifically of entrepreneurship, is investigated on the level of unemployment in the UK. The question is to what extent entrepreneurship, i.e., business ownership can reduce the level of unemployment. The alleged differences between the managed and the entrepreneurial economy will be discussed as well as the links between entrepreneurship and unemployment. It will be concluded that the UK is a relative outlier when using a simple model of the relationship between unemployment and the rate of business ownership. The model is calibrated using recent data of some 23 OECD countries. It underestimates the decrease in unemployment in the UK in the period 1982–1990. Some arguments are brought forward why this might be the case. 相似文献

Demand fluctuations and capacity utilization under duopoly 总被引:4,自引:0,他引:4
Summary. This paper studies the impact of uncertain demand on firms’ capacity decisions when they operate in an oligopolistic environment.
We define a two-stage game where firms choose capacity in the first stage without knowing which state of Nature is going to
realize, and output levels in the second, knowing which state is realized. We prove the existence of a symmetric subgame perfect
equilibrium at which firms are in excess capacity compared with the capacity they would choose in the Cournot certainty equivalent
game.

We model a two-period pure exchange economy where a risk averse manager, who has private information regarding future earnings, is required to issue an earnings report to investors at the end of each period. While the manager is prohibited from directly disclosing her private information, she is allowed to bias reported earnings in the first period, subject to GAAP rules that require that a specified proportion of the bias be reversed subsequently. We show there is a minimum threshold of reversal, such that, when the proportion of required reversal is above this threshold, the manager smooths income and communicates her private information through reported earnings. Consequently, the market attaches greater weight to reported earnings than under a regime that allows no discretion. When the required reversal is below the minimum threshold, the manager increases reported earnings without limit and the equilibrium degenerates. When the manager is not endowed with any private information, the market unravels the "true" earnings and price is unaffected by earnings management. Our results underscore the importance of both allowing and restricting reporting discretion through formal mechanisms. 相似文献

In this paper we analyze the properties of price equilibria in a duopoly market where firms sell vertically differentiated products, consumers being uncertain about which firm sells which quality. Both existence and properties of price equilibria are characterized by the beliefs of the consumers' population about the distribution of quality between firms. 相似文献

This paper presents MAcMap–HS‐6, a database providing a consistent, ad valorem equivalent measure of tariff duties and tariff rate quotas for 163 countries and 208 partners, at the six‐digit level of the Harmonized System (5111 products), accounting for all preferential agreements. We describe the methodology used to compute and aggregate an ad valorem equivalent of applied protection. Emphasis is placed on minimizing the endogeneity bias in the aggregation procedure, while acknowledging structural differences in export specialization. The resulting quantitative assessment is illustrated by giving an overview of applied protection across the world in 2001, in terms of average as well as distribution. 相似文献

This study investigated how partners' self-reported opportunism and shared decision making varied by culture in international joint ventures (IJVs) with the Japanese. Data were gathered by a mail survey of senior officials in IJVs located in 11 host countries. Significant differences were found between partners from Western cultures and the Japanese, but not between other Asians and the Japanese. Indirect effects suggest that shared decision making neutralizes cultural tendencies toward opportunism. Results indicated that opportunistic tendencies did not diminish as the IJV relationship aged, and that shared decision making did diminish as the relationship aged. 相似文献

This study analyzes the performance effects of proprietary, multihospital systems. It is shown that the organizational structure of these systems may affect the operating costs of member hospitals. Estimating a cost function for Florida hospitals and controlling for other factors, the average costs of HUMANA hospitals are empirically about 17 percent lower, while the costs of other leading chains are about 12 percent lower than not-for-profit institutions. These results contrast with earlier studies that found no such differences. Furthermore, the cost differential that exists between system and non-system hospitals can be largely attributed to technical efficiencies arising from chain ownership. 相似文献
